You can use the struct module to unpack an arbitrary sequence of bytes. You can find a very basic intro to struct in the File Handliung topic of my tutorial. But its not as simple as in C where you can more or less map a memory area onto a structuure, you'll need to extract each field and inert it into the equivalent Python data structure - but if that is a class you can write a method (load say?) to do the heavy work and just call load(file) or whatever when needed.
